LAMP AND, LANTERN.

To all 'it may concern: T

Be iff 'known thatI, How'arn .E. HA1:- BAUGH, acitizen of the United States, residing at Kenosha, in the county of Kenosha and State of -Wisconsin, have invented certaln new and useful Improvements in Lamps after set forth.

and Lanterns, specification.

()neof the objects of this invention is to produce an improved means-for forming a 'eparable 'connec tion between the oil font and the remainder of the lamp, the font and the burnergor any other two sections of a.

lamp or lantern.

Another bbj'ect i'sffto provide means for locking two separably connected lamp-sections against-separation. A further objectiis to'simplify the construction of lamp or lantern bodies.

The invention also relates to'the other anprovements in lamps and lanterns herein- In theaccompanying drawings, Figure 1 is a horizontal sectional View through. a lamp or lantern embodying the features of my invention, the View being taken upon the plane of dotted line 1 1 of Fig. 2. Fig. 2 is a vertical sectional viewupon the plane of dotted line 2 2 of Fig. 1. Fig. 3 is a section on dotted line 3 3 of Fig. 2, illustrating the separable connection between the oil font and the burner-section Fig. f is a frag-mental perspective View of. said burner section.

of which the following is a Patented June 8, 1909.

Serial no. 423,503. V

. upper end of the font is a rabbit forming an annular ,shoulderb which may be slightly concarc as illustrated in\Fig.' 2. The fiat upper wall 7 of the font .2 has a central opening in which is fixed a bushing 8, said hushed opening constituting, in this instance, a filling opening and also providing means for attaching the burner section 9 to the font. The burner section 9 has a central cylindrical neck 10 adapted to fit within the bushing 8. Surrounding said neck and preferably. fixed to the burner section is a packingring 11 of suitable material. The

neck 10 is provided with an annular depending flange 12 to which is secured, for example, by a screw-thread connection, a ring 13 carrying av plurality of lugs 14, three such lugs being used in the present instance. ithin the font and preferably 'attachedto the lower side of the wall 7 in any suitable way, as by soldering, is a plate 15 which may be of spring material and which has an opening 16 (Fig. 6) therein to receive the lowerend of the burner section. In the margin of the opening 16 is formed a plurality of notches 17, one end wall 18 of each notch being inclined as indicated in Figs. and 6. I The burner section 9 is secured to the font 2 by inserting the neck 10 into the bushing 8, the lugs 14 passing thro gh the notches 17, and then giving the burner section a partial rotation with relation to the font to carry the lugs let out of register with the notches 17,. said lugs engaging the inclined or cam end walls 18 of said notches and placing the plate 15 under tension, thereby insuring a fluid-tight joint between the font and the burner.

The lamp body comprises a cylindrical shell oropeirended tubular waist-19 which is preferably fonnied of sheet metal, the

lower edge of said shell being bent inward and upward to form a portion of double thickness, the lower end of said shell being adapted to rest upon theslu'mlder 6 of the. font 2. The double thickness just. referred ,to provides a space-ring or rollar :20.

The lamp body 1, and the font 2 are separably connected by means comprising three lugs 21 secured tothe font in any suitable way. asby foriningsaidlugs integral with ,a ring 22 and brazing or otherwisesecuring said ring to the lower surface of the wall? of sa id font,,thclugs21 extendingu nvardly llO from the font and having out-turned upper ends. A plate or ring 23, preferably of spring sheet metal, is secured to the lamp body 1n any suitable way as, for example, by forming ears 2% upon said plate and inserting said ears into recesses '25 in the shell 19. In the plate 23 is formed a plurality of notches 26 (Figs. 1 and 7)., each of said notches having a lock-strike incline27. and said plate being provided with stop shoulders 28, said notches being adapted to receive the lugs 21.

' Rotatably supported in the burner section 9 is a wick-moving shaft 29. The plate 23 has a down-turned lug 30 (Fig. 2) adapted to lie at one side of the shaft 29, and the shell 19 is grooved at 31 upon its inner face to receive the outer end of said shaft, the folded lower end of said shell being slotted at 32 to permit said shaft to be inserted upward into the shell 19 when the font is to be connected with the lamp body, which latter,

it will be remembered, in this particular embodiment, is assumed to be fixed in position.

Rotatably and slidably mounted in a bearing 33. in the shell 19 is a drive shaft 34: having at its outer end a'finger wheel 35 and at its inner end a gear wheel 36 meshing with a gear wheel 37 on the wick-moving shaft 29. Preferably, theteeth of the gears 36 and 37 are made V-form, as shown in Fig. 10, to facilitate their interengagement when the lamp body and the font are being connected. An opening 38 is formed in the plate 23 to accommodate the gears 36 and 37.

It is desirable that the shaft 29 and the lugs 21 occupy a certain relation to each other before the font is attached to the lamp body in order that said lugs shall enter the notches 2t and the shaft shall enter the slot 32 when the operator proceeds to connect the font to the lamp body. I therefore provide means for limiting the rotation of the burner with reference to the font when these two parts are being connected. Said means may consist of a lug 39 (Fig. 6) on the plate 15 arranged to be engaged by one of the lugs 14. When the last mentioned lug stops against the lug 39, the lugs 21 and the shaft 29 are in proper position to enter the notches 26 and the groove 31 when the font is to be connected to the lamp body.

'Assumingthe font to be disconnected from the remainder of the lamp, the burner section 9 maybe removed to permit the introduction of oil into said font, by giving said .burner section a partial rotation in the direction to' bring the lugs H into register with the notches 17. The burner section is then replaced and secured to the font by rotating the lugs 'l-l' into engagement with the lowerside of the spring plate 15 as shown in Fig. 5. one of the lugs '14- stopping against thc'lug SD. "The font. with its burner. may now be attached to the lamp body by insorting said burner into the lamp body, the lugs 21 being passed through the notches 2t and the outer end of the shaft 29 being placed in the slot'filil and the groove :31. The font is now partially rotated to engage the out-turned ends of the lugs 21 with the spring plate 23. the burner section 9 meanwhile being held from movement. by the engagement of the wick-moving shaft 29 with the walls of the groove 31 and the lug 30. The rotation of the lugs 21 is limited by the shoulders 2 but it will be understood that said lugs need not be rotated as far as said shoulders permit. The rotationof the lugs 21 out of register with the notches it? is not of sufficient extent to carry the notches 11' back into register with the lugs ll, said notchcsbeing rotated into the position shown in Fig. 3. The engagement of the lugs '21 with thespring plate 23 draws the font into lirm contact with the lamp body.

If desired. a positive lock may be pro- 7 vided for preventing separation of the oil font from the remainder of the lamp. The means herein shown for this purpose comprises a latch 40 pivoted to the plate '2 at .1. saidlatch carrying :1 lug 42 adapted to operative position. the font may be partially rotated to carry the lugs 21 into register with the notches 2t) whereupon the font may b lowered awav from the lamp body.

.When attaching the font the latch 40 may be held' by the operator in its inner position. or the upper side of the adjacent lug ll may be made sloping so as to push aside the latch without the direct intervention of the opcrator;

ll will be observed that the upper end of the oil font 2 fits within the lower end 20 of the lamp body, that said lower end is of double thickness. and that itis not weal;- cned by being cut away or notchcd to receive fastening devices on the oil font.

\l'hilc l have hcreinbcforc described my invention as applied to an automobile lamp, it is obvious that it may be applied to lamps or lanterns of various forms.
